How many degrees is required for freezing in the fluidity of jet fuel No. 3?

How many degrees is required for freezing in the fluidity of jet fuel No.
3? No.
3 jet fuel is one of
the petroleum products.

It is aviation kerosene
.

High calorific value, good combustion performance, rapid, stable, continuous and complete combustion, and small combustion area, less carbon deposit, not easy to coke; Good low temperature fluidity, which can meet the requirements of oil fluidity in cold and low temperature areas and high-altitude flight; Good
thermal and oxidation stability.

According to the standard requirements of GB6537 jet fuel, the freezing point is not higher than -47 ° C
.

This fluidity is the freezing point detection method is the use of GB/T2430 this standard to detect, automatic freezing point tester SH128 is in accordance with GB/T2430 this standard to design and produce, the test instrument using a microcontroller control, put into the sample, automatically out of the results, automatic printing
.

Jet fuel requires a low freezing point, and the fuel for long-term flight at high altitude should be less than -50 °C (short flight can not be higher than -40 °C).


There is also the same as the freezing point, but the definition of different indicators of the crystallization point, it refers to the fuel cooling when the temperature of the initial emergence of hydrocarbon crystallization, 1 ~ 3 °C lower than the measured value of the freezing point, for China, the Soviet Union and Eastern European countries to use
.

In recent years, China has begun to adopt freezing points instead of crystallization points
